OK There ARE American paying jobs in the DR in the teaching field which pay a comparable salary to the US.. BUT you have to be hired in the United States. I would assume that you would have to have not only a college degree but experience in teaching and perhaps even a master's degree.
There are jobs here in teaching and call centers. The teaching jobs for local hires can pay up to US $900 or $1500 a month if you qualify.
There are also American companies, such as AmBev, which have bought local Dominican companies which may be looking for American workers, if you have a good resume and are bilingual.
My hope is that you are perhaps a native Spanish speaker and are already in the high income bracket, so you might have a great resume, since the bottom 47% are not worried about taxes.
There was a recent sweep of American companies buying Dominican ones, so do a google search and see what that turns up.
The trick is that you must be hired there. If you try to get hired here, you will be paid like a local.
